icncREAmfcAnroN-FILLING nnvicn Application led March 24, 1924. Serial No. 701,413,

To all whom t may concern.'

' lBe it known that'we, BURTON L. HUNT- vLEY and JUSTICE C. IRWIN, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Ice-Cream-Carton- Filling Devices; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap ertains to make and use the same.

ur invention provides an extremely simple and eflicient ice cream carton filling device and, generally stated, consists of the novel construction,l combinations and arrangements of arts hereinafter described and'def'ined in t e claims.

As a very common and rapidlyI increasing commercial practice, ice cream is being soldr in cylindrical paper cartons.' These cartons, as usually made, are provided with one fixed and one detachable telescopic head and the cartons have been filled from a ladle or spoon, an operation requiring considerable time and much manipulation by way of digging the ice cream out of the can and packing the saine in the carton. Such pack-l ing operation requires considerable time and unless great care is taken, the ice cream will not be well packed in the carton.

Our invention provides an extremely simple device, whereby a paper cylindrical carton, such as usually employed, exce t that it is provided with two te escopic hea s, ma be very quickly and completely filled.

' llhe improved device comprises a cylindrical casing and a detachable cylinder head. The cylinder, at its open end, is provided'with a cutting edge of novel and peculiar construction, and the cylinder head iis] provided with a suitable operating han- In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views..

Referring to the drawings:

Fig. 1 is a view chiefly inaxial section, but with some parts in full elevation, showing the complete carton-filling device with a cylindrical-carton contained therein ready for filling;

Fig. 2 is a horizontal section on the line 2-2 of Fig. l;

Fig. 3 is a fragmentary section on the line 3-3 of Fig. l; f

Fig. 4 is an enlarged fragmentary sec tion on the line 4--4 of Fig. 1; f Fig. 5 is a fragmentary elevation showing parts in the vicinity of the line marked 5-5, adjacent to Fig. l; and

Fig. 6 is a section corresponding to Fig. 1, but showing the carton filled with ice cream, the head of the cylindrical casing being detached;

The cylindrical paper carton is indicated' by the character A. The cylindrical casing 7 is a thin sheet metal shell, preferably of sheet steel nickel-plated, and is of such diameter that the carton A can be freely slid into and out ofthe saine. The cylindrical casing 7, at its lower end, is provided with a sharp or made conical in both directins from said cutting edge, so thatl it' forms an internal annular stop shoulder or ledge 9 and an exteinal annularledge 10. The internal ledge 9 aords a stop limiting the downward movement of the carton A within the cylindrical casing 7 and said casing 7 is of such length above said ledge 9 that the carton will project far enough out of said casing to permit the same to be readily engaged for the purpose of removing the filled carton.` It is highly important to note, however, that the ledge 9 interior of e carton, so that in passing through the ice-cream contained in the can, it will cut a cylindrical body of ice cream of slightly less diameter than the interior of said carton. This is important because .it prevents friction between the linterior of the carton and the exterior of the ice cream plug cut from the can. The outwardly projecting annular ledge is important for a similar reason, to wit: that it enlarges the hole cut in the body of ice cream from which the plug is taken beyond the diameter of the exterior of the, cylindrical shell 7, and thus prevents friction between the ice cream and shell. here it may be stated that, before these internal and external annular ledges Were applied, the friction between the ice cream, the shell, and carton was found so great that it was impracticable to use the cutting edge 8 and isbeveled plrojects slightly inward of the t erated easily and in the most satisfactory' manner.

As a cutting device operative to sever the plug from the body of the ice cream in a can by rotation of the cylindrical shell and its contents, we provide a small wire 11 extended diametrically across the lower end of the cylindrical shell 7 -and with its ends anchored through the diametrically opposite points, preferably in the plane of the ledge 9.

The cylindrical shell is provided with a detachable cylinder head 12 having a depending annular flange 13 adapted to be telescoped over the upper end of said cylindrical shell and to be detachably secured thereto by bayonet joints 14. This head, when applied, will hold the carton A within the cylindrical shell 7 with its lower end nearly or quite seated on the internal annular ledge 9, as best shown in Fig. 1. Preferably, the cylinder head 12 is provided with a long axially projecting handle in the form of a metal tube 15, the lower end of which is soldered, brazed, or otherwise rigidly secured to said head, and the upper end of which is shown as provided with a tubular transverse hand piece 16. The head 12 is4 shown as provided with several air-venting 'perforations 17 and with a glass-covered sight opening 18, through which latter the operator may observe when the carton has been completely filled with ice cream.

The operation is probably obvious from the foregoing statements. When the carton is placed in the ller, as shown in Fig. 1, it may be filled simply by pressin thecylindrical casing 7 downward into a ody of ice cream and the air displaced by the ice cream will find ready escape through the air vents 17. When the carton has been filled and the device removed therewith and the head 12 detached from the cylindrical casing, the filled carton ma be readily removed from the casing and tlie carton heads or caps, not shown, will then.be applied, thereby closing the carton with its contents.

The above device has, in practice, been found highly eiiicient for the purposes had in view.

What we claim is:

1. An ice cream carton liller comprising a cylindrical shell having a beveled annular cutting edge at one end and a detachable head at its other end on the outside thereof, the said head when applied serving to hold a cylindrical carton within said shell, said head having an Aoperating handle and arranged to extend beyond the casing end to permit an extension of the cylindrical carton beyond said end.

2. An ice cream cartonfilling device comprising a true cylindrical metallic shell provided at oneend with an annular cutting edge and beveled in both directions from said cutting edge to form internal and eX- ternal annular ledges, said external ledge havlilng a greater diameter than that of the s e 3. An ice cream carton filling device comprising a true cylindrical shell provided at one end with an annular cutting surface beveled in both directions from its cutting edge, the outer portion of said beveled surface having a diameter greater than that of said cylinder and the inner portion of said beveled surface forming a stop shoulder for a cylindrical carton and having a diameter materially less than the carton so that the ice cream body inserted into said carton will have a diameter less than that of the interior of said carton.

In testimony whereof we aiiix our signatures.
